4. The number equaling FS is the full scale flow rate of the unit and 0 0 is the percentage of the set point from 0 100 So for an example using FS 160 SLPM if you adjust the set point to 80 00 on the Set line you will simultaneously see the percentage change to 50 as 80 is half of 160 Pressing the button under Setup1 will switch the display to Setup2 Setup 2 displays Control Algorithm Type PDF or PD2l and the values for the Proportional Differential and Integral terms and Autotare On or Off The PDF algorithm is the standard PID algorithm used on most controllers This is explained on page 13 of this manual The PD2l algorithm is used primarily for high performance pressure and flow control applications When this algorithm is selected via control Setup2 the T gain value is forced to a numerically odd value ending in 1 3 5 7 or 9 This algorithm exhibits two basic differences from the standard PID algorithm that most controllers utilize 1 Instead of applying a damping function based upon the rate of change of the process value it applies a damping function based upon the square of the rate of change of the process value 2 The damping function is applied directly to the proportional error term before that term is used in the proportional and integral functions of the algorithm This provides a certain amount of look ahead capability in the control loop 20 Because of these differences you will

6. A good rule of thumb is At a given flow rate the higher the viscosity the higher the indicated flow Volume Flow vs Mass Flow At room temperature and low pressures the volumetric and mass flow rate will be nearly identical however these rates can vary drastically with changes in temperature and or pressure because the temperature and pressure of the gas directly affects the volume For example assume a volumetric flow reading was used to fill balloons with 250 mL of helium but the incoming line ran near a furnace that cycled on and off intermittently heating the incoming helium Because the volumetric meter simply measures the volume of gas flow all of the balloons would initially be the same size However if all the balloons are placed in a room and allowed to come to an equilibrium temperature they would generally all come out to be different sizes If on the other hand a mass flow reading were used to fill the balloons with 250 standard mL of helium the resulting balloons would initially be different sizes but when allowed to come to an equilibrium temperature they would all turn out to be the same size This parameter is called corrected mass flow because the resulting reading has been compensated for temperature and pressure and can therefore be tied to the mass of the gas Without knowing the temperature and pressure of the gas and thus the density the mass of the gas cannot be determined 29 Once the corrected mass
7. Therefore in order to determine mass flow rate two correction factors must be applied to volumetric rate temperature effect on density and pressure effect on density Compressibility Heretofore we have discussed the gases as if they were Ideal in their characteristics The ideal gas law is formulated as PV nRT where P Absolute Pressure V Volume or Volumetric Flow Rate n number moles or Molar Flow Rate R Gas Constant related to molecular weight T Absolute Temperature Most gases behave in a nearly ideal manner when measured within the temperature and pressure limitations of Alicat products However some gases such as propane and butane can behave in a less than ideal manner within these constraints The non ideal gas law is formulated as PV ZnRT Where Z is the compressibility factor This can be seen in an increasingly blatant manner as gases approach conditions where they condense to liquid As the compressibility factor goes down Z 1 is the ideal gas condition the gas takes up less volume than what one would expect from the ideal gas calculation 30 This reduces to Pa Val Za Ta Ps Vs Zs Ts eliminating R and n Alicat mass flow meters model gas flows based upon the non ideal gas characteristics of the calibrated gas The flow corrections are normally made to 25 C and 14 696 PSIA and the compressibility factor of the gas under those conditions This allows the user to multiply the mass fl

18. note the following 1 Increasing P gain can be used to damp out overshoot and slow oscillations in pressure controllers You will know that P gain is too high when the controller breaks into fast oscillations on step changes in set point On flow controllers too high a P gain results in slower response times Too low a P gain results in overshoot and or slow oscillation A good starting value for P gain is 200 2 If the unit was originally shipped with the PD2I algorithm selected the D gain value should be left at or near the factory setting because it relates primarily to the system phase lags If you are changing from the default algorithm to the PD2I algorithm you should start with a D gain value of 20 3 The T gain is used to control the rate at which the process converges to the set point after the initial step change Too low a value for I gain shows up as a process value that jumps to near the set point and then takes awhile to converge the rest of the way Too high a value for T gain results in oscillation A good starting value for the I gain is 201 Caution Valve tuning can be very complex If you would like assistance please contact Alicat for technical support AUTO Autotare is a function that automatically tares the controller when a zero set point is given Control Setup2 shows a line marked AUTO In parenthesis you see ON or OFF to signify the current setting With
